Dynamic pin configurator
A method and apparatus to protect the coded signals sent over physical twisted-pair wiring or between two (2) or more LANs connected by a Wide Area Network (WAN), from unauthorized electronic circuit/wiring monitoring. This is accomplished by varying the assignments of the standard Registered Jack communication pins, varying the transmission speed, inserting meaningless or unrelated data, encrypting data before it is sent or changing network protocol(s) on behalf of the communications adapter/controller of each computer to which it is attached on those LANs.
1. A method for securing a computer LAN having a number of network assets connected, comprising:
a. verifying that a fully configured male, 8P8C connector is inserted into a female, 8P8C LAN connector of a first network asset;
b. generating a public key default for use by a Diffie-Hellman exchange;
c. setting a time-to-live for the Diffie-Hellman public key;
d. setting a synchronization time-to-live on the Diffie-Hellman public key;
e. performing a Diffie-Hellman exchange to exchange the public key default with a next in line network asset;
f. creating a crypto-null packet;
g. changing the network protocol based on the use of a random number generator;
h. changing the pin assignments on the 8P8C LAN port, thus increasing the number of possible connections to be monitored by an intruder;
i. setting the transmission speed based on the use of another random number generator, resulting in a transmission speed value; and
j. communicating through the LAN port to a next in line receiving network asset as to what the new protocol and pin assign assignments are for the 8P8C LAN port by performing a Diffie-Hellman exchange, as defined above, using the above generated pin assignments.
2. The method according to claim 1 wherein step a) is achieved by performing a floating-pin grounding test in which several varying voltages are used on each pin position to determine whether or not the electrical circuit is grounded for that pin position.
3. The method according to claim 1 wherein said public key default of step b) is generated based on a random number generator.
